Landcruiser GDJ79 Ute, 2.8L TD, 2023-Current, 3in Turbo Back Without Cat & Without Muffler (MKTY0405).
Category: Mufflers and resonators


No cat, no muffler — the MPI Automotive MKTY0405 is the fully open 3in turbo-back for the Toyota Landcruiser GDJ79 2.8L turbo-diesel ute from 2023. With nothing in the run to silence and no cat ahead of it, it is the least-restricted and hardest-sounding build in this GDJ79 range.
Stripping out both the muffler and any resonator leaves a clean 3in path from the turbo back, the freest-flowing layout of the GDJ79 options and the rawest in tone. It is the deliberate pick for a build chasing maximum flow and the hardest note, accepting there is nothing in the system to subdue the 2.8L diesel and no drone control on the highway.
This build runs without the catalytic converter. Removing the cat from the engine-back run means it is not ADR 79/04 compliant for road registration in NSW and is for off-road use only. On a modern diesel ute that is the line that settles registration, so speak to the workshop about your intended use before ordering.
Turbo-back means the run is replaced from the turbo outlet rearward, a longer span than a rear-section swap. At 3in the MKTY0405 covers that full run on the GDJ79 2.8L ute from 2023, finished open at the rear. MPI Automotive lists it at $2387.98, generally ordered in to suit your build.
